The line is a multipurpose equipment allowing to manufacture semitrailer girders with the height 380-700mm, length – up to 14000mm.
Description of equipment operation
Girders assembly and their automatic welding from the front side is performed on the first position, then an integrated positioner rotates the item by 180° and the welding of the girder from the reverse side takes place.
In order to ensure a necessary clamping force, hydraulic clamps are used.
By moving hydraulic clamps mounted on the line, by changing supporting elements involved in forming of girder flange configuration, an opportunity to assembly items of different geometry in the dimensions range stated above is created.
Automatic welding is performed by means of a mobile gantry plant. Actuating of a gantry and torches is performed by means of servo drives, which ensures travel and positioning accuracy.
Due to the secure fixation of all the girder elements, there is no more need in subsequent straightening and leveling of the welded item.
